NUMERICAL SIMULATION IN ROLL PASS DESIGN FOR …
The application of finite element simulation to the problem of roll pass design for round bar rolling is considered. Two roll pass sequences were developed by analytical methods and then optimized using 2.5D Finite Element Method (FEM). The first one is a classical oval-round roll pass design. The second one is a combination of flat rolls and ...

Plastic work approach for surface defect prediction in the hot bar
The prime objective of this research work is to formulate a process design of multi-pass bar rolling process with less instability. In order to achieve this goal, specific plastic work for judging unstable conditions was used as a criterion, followed by the earlier work by Lee et al. (2007).Based on the specific plastic work approach proposed, better …
